Nobel laureate John Jumper leaves Google DeepMind after nine years to join Anthropic

John Jumper — the computational chemist who co-created AlphaFold and shared the 2024 Nobel Prize in Chemistry — announced on June 19, 2026 that he is leaving Google DeepMind after nearly nine years to join Anthropic. Jumper made the announcement in a post on X, joining a week in which the broader AI industry watched another major departure from Google: Noam Shazeer, Gemini co-lead and transformer co-inventor, left for OpenAI.

What's new

Jumper spent nearly nine years at Google DeepMind, where he led the AlphaFold team from an early-stage project to the landmark model that predicted over 200 million protein structures. The AlphaFold work earned Jumper and DeepMind CEO Demis Hassabis the Nobel Prize in Chemistry in 2024 — the most prominent scientific honor ever tied to AI research.

Jumper described his time at DeepMind warmly in his departure announcement: "GDM is a special place, and I'll still be excited to hear about what amazing things they discover next."

Neither Anthropic nor DeepMind publicly commented on the move. Jumper said he would be taking time to recharge before starting at Anthropic and did not disclose the specifics of his role.

Context

Jumper's departure lands in an extraordinary week for AI talent movement out of Google. The same week, Noam Shazeer — who helped create the transformer architecture underlying most modern AI and co-led Google's Gemini program — announced he was joining OpenAI. The back-to-back departures represent two of the most credentialed AI researchers in the world moving from Google to Anthropic and OpenAI respectively.

Jumper's move is distinct from Shazeer's: where Shazeer is a foundational figure in language modeling, Jumper's credentials are in AI-for-science, specifically protein structure prediction and biological AI. Anthropic has been building out its science capabilities throughout 2026 — opening wet labs, publishing research on AI agents for biological workflows, and announcing flagship research partnerships earlier in the year.

Why it matters

Jumper is the most decorated individual scientist to change employers mid-career in the AI industry. A Nobel laureate joining Anthropic gives the company something no benchmark score can supply: institutional scientific legitimacy. It signals that Anthropic is increasingly positioning itself as a serious AI-for-science organization, not just a safety-focused language model lab.

For Google DeepMind, the loss of both Shazeer and Jumper in the same week — two of the most recognizable names in the company's history — marks a notable moment in the ongoing talent competition among frontier labs. DeepMind built its scientific reputation substantially on the AlphaFold result; Jumper was the lead scientist on that work.
